ssh failure when attempting to install cargo-watch

[joprice]

I get the error below when trying to install cargo-watch:

cargo binstall cargo-watch
11:17:18 [INFO] Installing package: 'cargo-watch'
Error: authentication required but no callback set; class=Ssh (23)

I found this related issue rust-lang/git2-rs#329.

hmm, it shouldn't be using git to install cargo-watch, and seems to work okay from here :-/
could you try with --log-level debug and attach the log as a file here?

Maybe it has something to do with my local setup.

13:50:38 [INFO] Installing package: 'cargo-watch'
13:50:38 [DEBUG] (1) cargo_binstall::drivers: Updating crates.io index
Error: authentication required but no callback set; class=Ssh (23)

Caused by:

oh interesting, we do use git to fetch the crates.io registry via the crates_index package. i suspect maybe you have some local configuration that is forcing this to attempt to fetch via ssh instead of http?

it would be interesting to know how cargo behaves in comparison, --log-level trace may also be helpful but, tends to be unreasonably verbose.

This is indeed the cause of the issue for me but shouldn't cargo handle that (e.g, with ssh) as well?

Upstream issues: frewsxcv/rust-crates-index#37 and rust-lang/git2-rs#600.

There's some suggestion that gitoxide might not have this issue, if that's indeed the case there may be a way forward without waiting on git2-rs (which has some other issues, e.g. failing when the dynlib version bumps, as recently happened)

This would be gone crates_index would be removed, right?
